Description

Bloc robinet pour récipient de gaz à sécurité d'utilisation améliorée  Faucet block for gas container with improved safety of use
L'invention concerne un bloc robinet, avec ou sans système de détente intégré, pour récipient de gaz sous pression, telle une bouteille de gaz, muni d'un système de commande électronique permettant de piloter un dispositif actionneur commandant les déplacements d'un organe mécanique mobile de manière à bloquer ou libérer l'organe de manœuvre, tel un volant rotatif ou un levier pivotant, du système de sélection et/ou de réglage du débit de gaz. The invention relates to a valve block, with or without an integrated expansion system, for a pressurized gas container, such as a gas cylinder, provided with an electronic control system for controlling an actuator device controlling the movements of an organ. mechanical moving so as to block or release the operating member, such as a rotary wheel or a pivoting lever, the selection system and / or gas flow control.
Les gaz et mélanges de gaz à usage médical habituellement conditionnés dans des récipients de gaz, telles des bouteilles de gaz, peuvent présenter plusieurs contraintes ou propriétés compliquant leur utilisation.  Medical gases and gas mixtures usually packaged in gas containers, such as gas cylinders, may have a number of stresses or properties that complicate their use.
On peut citer par exemple une durée de péremption au-delà de laquelle un gaz ou mélange gazeux ne doit plus être utilisé, ou des conditions extérieures rendant un gaz ou mélange gazeux impropre à une utilisation médicale, par exemple le phénomène de « démêlage » à température ambiante négative (i.e. < 0°C) des mélanges O2/N2O. For example, an expiry time beyond which a gas or gaseous mixture must no longer be used, or external conditions making a gas or gaseous mixture unfit for medical use, for example the phenomenon of "disentangling" to negative ambient temperature (ie <0 ° C) of O 2 / N 2 O mixtures.
Il existe des moyens permettant d'empêcher une utilisation non appropriée d'un tel gaz ou mélange gazeux, comme apposer un étiquetage sur les emballages ou récipients indiquant la date de péremption du gaz, ou utiliser un ou des témoins visuels et/ou sonores indiquant une exposition du récipient de gaz à des conditions extérieures prédéfinies, par exemple des températures négatives.  There are ways to prevent improper use of such a gas or gas mixture, such as labeling the containers or containers indicating the expiry date of the gas, or using a visual and / or audible indicator (s) indicating exposure of the gas container to predefined external conditions, for example negative temperatures.
Toutefois, ces moyens se limitent à donner une information à l'utilisateur et leur efficacité est donc soumise à l'attention de l'utilisateur. En d'autres termes, un utilisateur qui ne prêterait pas attention à la date de péremption d'un gaz ou à un témoin visuel ou sonore, prend le risque d'administrer un gaz ou mélange gazeux impropre à un patient, avec tous les risques et conséquences qui en découlent.  However, these means are limited to giving information to the user and their effectiveness is therefore subject to the attention of the user. In other words, a user who does not pay attention to the expiry date of a gas or a visual or audible indicator, takes the risk of administering a gas or gas mixture unsuitable for a patient, with all the risks and consequential consequences.
Au vu de cela, le problème qui se pose est d'empêcher une utilisation d'un gaz ou mélange de gaz dont l'administration pourrait faire courir un risque au patient, ledit gaz ou mélange de gaz étant délivré par un bloc robinet équipant un récipient de gaz, telle une bouteille de gaz. La solution de l'invention est un bloc robinet pour récipient de gaz, telle une bouteille de gaz, sous pression comprenant : In view of this, the problem is to prevent the use of a gas or gas mixture, the administration of which could put the patient at risk, said gas or mixture of gases being delivered by a valve block equipping a gas container, such as a gas cylinder.

- un système de sélection et/ou de réglage du débit de gaz comprenant un organe de manœuvre mobile actionnable par l'utilisateur et coopérant avec le système de contrôle de gaz pour contrôler et/ou régler le débit de gaz sortant par l'orifice de sortie de gaz,  a system for selecting and / or regulating the gas flow rate, comprising a mobile actuating member operable by the user and cooperating with the gas control system for controlling and / or regulating the flow of gas exiting through the orifice of gas outlet,

De façon classique, un passage interne 2 de gaz relie fiuidiquement un orifice d'entrée 10, porté par l'expansion filetée 1 de forme tronconique, à un orifice de sortie 11 de gaz, porté par un raccord de sortie 9 auquel vient se fixer une canalisation de gaz, par exemple un conduit flexible, ou un autre appareil, tel un débitmètre, un détendeur ou autre. Ce passage interne 2 de gaz permet d'acheminer le gaz entre la bouteille 20 et le raccord de sortie 9.  Conventionally, an internal passage 2 of gas fluidly connects an inlet port 10, carried by the frustoconical threaded expansion 1, to an outlet orifice 11 of gas carried by an outlet fitting 9 to which is fixed a gas line, for example a flexible conduit, or another device, such as a flow meter, a pressure reducer or the like. This internal passage 2 of gas makes it possible to convey the gas between the bottle 20 and the outlet fitting 9.
On voit en outre qu'un système de contrôle de gaz 3 est agencé sur le passage interne 2 de gaz, permettant de contrôler et/ou de régler le débit de gaz circulant dans le passage interne 2 de gaz. En effet, selon le mode de réalisation choisi, le système de contrôle de gaz 3 peut être conçu pour permettre une libération du gaz :  It is further seen that a gas control system 3 is arranged on the internal gas passage 2, for controlling and / or adjusting the flow rate of gas flowing in the internal gas passage 2. Indeed, according to the chosen embodiment, the gas control system 3 can be designed to allow a release of the gas:
- soit de type tout ou rien, Le., ouvert ou fermé, c'est-à-dire que le gaz peut être stoppé ou libéré sans contrôle de son débit. Dans ce cas, l'organe de manœuvre 4, préférentiellement un volant ou un levier, agit sur un élément mobile pour libérer le passage de gaz lorsqu'une circulation du gaz est souhaitée ou, à l'inverse, obturer le passage de gaz lorsqu'aucune circulation du gaz n'est voulue.  - Or all-or-nothing, Le., open or closed, that is to say that the gas can be stopped or released without control of its flow. In this case, the operating member 4, preferably a steering wheel or a lever, acts on a movable element to release the gas passage when a flow of gas is desired or, conversely, close the gas passage when no gas flow is desired.
- soit avec possibilité d'ajuster le débit de gaz passant au travers dudit système de contrôle de gaz 3 entre plusieurs valeurs de débit (i.e. >2) correspondant à plusieurs positions d'un élément mobile d'obturation, y compris une position dite « 0 » ou « fermée », dans laquelle le débit de gaz est nul et, à l'opposé, une position d'ouverture maximale, dans laquelle le débit de gaz libéré atteinte une valeur maximale de débit désiré, et plusieurs positions intermédiaires. Là encore, le contrôle du débit se fait via l'organe de manœuvre 4, préférentiellement un volant ou un levier, qui va agir sur un élément mobile agencé sur le passage de gaz 2 pour ajuster le débit entre les différentes valeurs de débit possibles. Le système de sélection et/ou de réglage du débit de gaz comprend donc un organe de manœuvre 4 mobile, à savoir un volant rotatif sur la Figure ci-annexé, qui est actionnable par l'utilisateur et vient coopérer avec le système de contrôle de gaz 3 pour contrôler et/ou régler le débit de gaz sortant par l'orifice de sortie 1 1 de gaz porté par le raccord de sortie 9. or with the possibility of adjusting the flow rate of gas passing through said gas control system 3 between several flow rate values (ie> 2) corresponding to several positions of a movable closure element, including a position called " 0 "or" closed ", wherein the gas flow is zero and, in contrast, a maximum open position, wherein the released gas flow reaches a desired maximum flow rate, and several intermediate positions. Again, the flow control is via the operating member 4, preferably a wheel or a lever, which will act on a movable member arranged on the gas passage 2 to adjust the flow between the different possible flow rates. The system for selecting and / or regulating the gas flow therefore comprises a movable operating member 4, namely a rotary flywheel in the attached figure, which can be actuated by the user and cooperates with the control system. gas 3 for controlling and / or regulating the outgoing gas flow through the outlet port 1 1 of gas carried by the outlet fitting 9.
Le bloc robinet 1 comprend par ailleurs un système de commande électronique 7, 7', 8 permettant de piloter un dispositif actionneur 5 conçu pour commander le déplacement d'un organe mécanique 6 mobile en réponse à un signal de pilotage délivré par le système de commande électronique 7, 7', 8.  The valve block 1 also comprises an electronic control system 7, 7 ', 8 for controlling an actuator device 5 designed to control the movement of a mobile mechanical member 6 in response to a control signal delivered by the control system. electronic 7, 7 ', 8.
Le système de commande électronique 7, 7', 8 comprend une carte électronique 8.  The electronic control system 7, 7 ', 8 comprises an electronic card 8.
Dans le mode de réalisation proposé, au moins un capteur 7, 7', par exemple un capteur de pression 7 ou de débit et/ou un capteur de température 7' ou de position, est relié à la carte électronique 8 de manière à récupérer les signaux de mesure provenant dudit capteur 7, 7'. Le dispositif actionneur 5 est aussi relié électriquement à la carte électronique 8.  In the proposed embodiment, at least one sensor 7, 7 ', for example a pressure sensor 7 or a flow sensor and / or a temperature sensor 7' or a position sensor, is connected to the electronic card 8 so as to recover the measurement signals from said sensor 7, 7 '. The actuator device 5 is also electrically connected to the electronic card 8.
Bien entendu, d'autres types de capteurs adaptés pourraient être utilisés.  Of course, other types of suitable sensors could be used.
Une source d'alimentation électrique 12, par exemple une batterie rechargeable ou non, une pile ou un condensateur, alimente la carte électronique 8 en courant électrique.  A power supply 12, for example a rechargeable battery or not, a battery or a capacitor, supplies the electronic card 8 with electrical current.
L'organe mécanique 6 mobile en translation ou en rotation, telle une tige, une clavette ou un pion ou une goupille, agit sur l'organe de manœuvre 4, à savoir ici le volant rotatif, en réponse à son actionnement par le dispositif actionneur 5, de manière à bloquer ou à libérer l'organe de manœuvre 4.  The mechanical member 6 mobile in translation or in rotation, such as a rod, a key or a pin or a pin, acts on the operating member 4, namely here the rotary wheel, in response to its actuation by the actuator device 5, so as to block or release the operating member 4.
Sur la Figure, l'organe de manœuvre 4 est un volant rotatif agencé autour du raccord de sortie 9 portant l'orifice de sortie de gaz 11 et situé sur la face avant du bloc robinet 1. Toutefois, ce mode de réalisation n'est pas exclusif et le raccord de sortie 9 et/ou l'organe de manœuvre 4 pourraient être agencés différemment et/ou à un autre endroit sur le bloc robinet 1.  In the Figure, the operating member 4 is a rotating wheel arranged around the outlet fitting 9 carrying the gas outlet port 11 and located on the front face of the valve block 1. However, this embodiment is not exclusive and the outlet connector 9 and / or the operating member 4 could be arranged differently and / or at another place on the valve block 1.
En d'autres termes, l'organe mécanique 6 dont le déplacement est commandé par le dispositif actionneur 5, peut se déplacer entre au moins deux positions comprenant une position active, dans laquelle elle assure un blocage de l'organe de manœuvre 4 et donc de l'élément mobile du système d'ouverture et/ou de réglage du débit, conduisant ainsi à l'impossibilité pour l'utilisateur de libérer le passage du gaz vers le (ou les) raccord de sortie de gaz 9, sans une opération particulière à effectuer par l'utilisateur ou un opérateur de maintenance. Le bloc robinet 1 peut aussi comprendre un dispositif de mémorisation d'informations reliée électriquement au système de commande électronique 7, 7', 8, par exemple une mémoire de stockage contenant une ou des informations utiles, comme une date de péremption du gaz ou de maintenance du bloc robinet 1. Une telle information peut être également utilisée par la carte électronique 8 pour commander le dispositif actionneur 5 et l'organe mécanique 6 pour bloquer l'organe de manœuvre 4 et donc toute libération du gaz, par exemple lorsque la date de péremption est atteinte ou dépassée. In other words, the mechanical member 6 whose displacement is controlled by the actuator device 5, can move between at least two positions comprising an active position, in which it ensures a locking of the operating member 4 and therefore of the mobile element of the opening and / or flow control system, thus leading to the impossibility for the user to release the passage of the gas to the (or) gas outlet connection 9 without an operation particular to be performed by the user or a maintenance operator. The valve block 1 may also include an information storage device electrically connected to the electronic control system 7, 7 ', 8, for example a storage memory containing one or more useful information, such as a gas expiry date or maintenance of the valve block 1. Such information can also be used by the electronic card 8 to control the actuator device 5 and the mechanical member 6 to block the operating member 4 and therefore any release of the gas, for example when the date expiry date is reached or exceeded.
De manière générale, les informations ou mesures provenant du (ou des) capteur(s) 7, 7' et/ou de la mémoire de stockage sont recueillies et traitées par la carte électronique 8 qui va commander automatiquement, en réponse auxdites informations ou mesures, le dispositif actionneur 5 qui va aller agir sur l'organe mécanique 6 pour bloquer ou, à l'inverse, libérer l'organe de manœuvre 4 du système de sélection et/ou de réglage du débit de gaz et dès lors, selon le cas, autoriser ou interdire toute libération de gaz par le bloc 1.  In general, the information or measurements originating from the sensor (s) 7, 7 'and / or from the storage memory are collected and processed by the electronic card 8 which will automatically control, in response to said information or measurements. , the actuator device 5 which will act on the mechanical member 6 to block or, conversely, release the operating member 4 of the selection and / or gas flow control system and therefore, according to the allow or prohibit any release of gas from Block 1.
Ceci permet d'éviter une utilisation du gaz provenant de la bouteille 20 lorsque son administration pourrait faire courir un risque au patient, par exemple en cas de date de péremption dépassée ou en cas de dé-mélange d'un mélange N2O/O2 du fait d'une exposition de la bouteille 20 à une température trop basse (<0°C), puisque ces 'incidents' seraient détectés automatiquement par la carte électronique 8 du bloc robinet 1 et celle-ci commanderait alors immédiatement un blocage de toute rotation du volant de manœuvre 4 empêchant ainsi toute libération du gaz. This makes it possible to avoid the use of the gas coming from the bottle 20 when its administration could put the patient at risk, for example in the event of an expired expiry date or in the case of de-mixing of an N 2 O / O mixture. 2 because of an exposure of the bottle 20 to a temperature too low (<0 ° C), since these 'incidents' would be detected automatically by the electronic card 8 of the valve block 1 and it would then immediately command a blockage of any rotation of the steering wheel 4 thus preventing any release of the gas.
Selon un mode de réalisation particulier, le bloc robinet 1 est de type RDI, c'est-à-dire robinet à détendeur intégré, c'est-à-dire qu'il comprend un système de réduction de la pression du gaz, par exemple un système à clapet de détente et siège de clapet, agencé sur le passage interne de gaz 2, entre les orifices d'entrée 10 et de sortie 11 , de manière à permettre de réduire la pression du gaz à haute pression (par exemple une haute pression de l'ordre de 200 à 300 bar) contenu dans la bouteille 20 à une pression d'utilisation ou basse pression (par exemple une basse pression de l'ordre de 1 à quelques bars).  According to a particular embodiment, the valve block 1 is of RDI type, that is to say integrated pressure reducing valve, that is to say that it comprises a system for reducing the pressure of the gas, by for example, an expansion valve and valve seat system, arranged on the internal gas passage 2, between the inlet and outlet orifices 11 and 11, so as to make it possible to reduce the pressure of the gas at high pressure (for example a high pressure of the order of 200 to 300 bar) contained in the bottle 20 at a pressure of use or low pressure (for example a low pressure of the order of 1 to a few bars).
Le bloc robinet 1 peut également comprendre un dispositif indicateur de pression 13, tel un manomètre, donnant à l'utilisateur une mesure de la pression du gaz au sein de la bouteille 20.  The valve block 1 may also comprise a pressure indicating device 13, such as a manometer, giving the user a measurement of the pressure of the gas within the bottle 20.
